on 02025-10-12#EEVblog #video about #low-power #LCD #displays (like 14.3μA at 3.3V, up to 25μA during updates, 2.9" diagonal and 384×168) and why he prefers them to #e-ink: e-ink takes tens or hundreds of milliamps for a second or two to update. And service life is only 5 years or 10 million switches. He’s going to try the nice high-resolution ST7305-based #good-display.com (Dalian Good Display Co., Ltd.) reflective active matrix TFT LCD, even though the MOQ is 1000, because they sent him a demo board. It’s a nice high-contrast black and white and a very wide viewing angle despite (I think?) not being #memory-LCD. @mikeselectricstuff says the ST7305 datasheet says it supports up to 30Mbps over SPI. @afreestone101 says that if you peel the polarizer layer off the memory LCDs, the black color becomes mirror shiny. #electronics #hardware
